ROOF-CARLINE.

Specification of Letters Patent Patented July 8,

Application filed October 25. 1905. Serial No. 284.278.

To all whom it may concern:

Be it known that I, GEORGE B. MALTBY, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Roof-Carlines, of which improvement the following is a specification.

My invention relates to sheet or plate metal roof-carlines of the general class or ty e which is exemplified in Letters Patent of the United States, N 0., 649,121, granted and issued to me and to Broderick Haskell (as assi nee of two-thirds the right) under date of m 8, 1900.

The object of my present invention is to provide a roof-carline embodying the advantages of that Letters Patent No. 649,171 aforesaid, and the further advantages of increased strength without substantial in crease of weight, and facilities for the reception of a wood filler, if desired.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view in elevation showing one-half in length of a roof-earline embodyin my invention;'Fig. 2, a plan or top view of the same; Fig. 3, an end View as seen from the left and Figs. 4, 5, and 6 transverse sections on the lines a a, b b, and c 0, respectively, of Fig. 1.

1n the practice of my invention I rovide a roof-carline which is formed of s wet or plate metal, preferably by being pressed or sha )cd in a di; or mold The bo( y 1 of the car me is integral and of channel form in transverse section and is suited to receive a filling 2, of-wood, for the attachment of roof members, said idling-piece fitting between the side llanges of the carline and being secured thereto preferably by bolt", as shown in Fig. 6. The body is downwardly inclined from its middle to each of its ends at such an angle as may be adapted to impart the desired pitch to the roof and in the instance shown is of uniform depth throughout, but it may, if preferred, be made of gradually-diminishing depth from its mi'ddle porti. n toward its ends.

The ends of thebody are turned into integral downwardlyrejecting end flanges 1, which are adapted to abut against the side plates of the car-frame and to be secured thereto by horizontal bolts. As shown in full lines in Fig. 1, the body is made of sufficient length to lit over end flanges in such. case almtting against the outer sides thereof; but, if prcfcrred, its length may be such that the end flanges will abut against lhc inncr side of the side plates, as indicated in dotted lines. The metal blank from which the carlincs are made is preferably cut out in such shape that when the carlinc is bent into desired form its vertical flanges shall be bent over into auxiliary llanges 1 which extend from its ends toward its n'iiddle mrtion into which they gradually merge. 'lhc [hinges 1 are turned downwardly with the motel of the main portion of the body in forming the end flanges 1, thcreby correspon:lingly increasing'the bearingsurface of the latter.

In order to impart increased strength and rigidity to the -arline without substantial increase of its weight, a central rib or corrugation 1", which may either be made by massing or folding the metal adjoining the tudinal center line of the body into two downwardly-projccting plates in contact one i with the other or preferably, as shown, into the side plates, the

two separated plates presenting a U or channel section, is formed upon the body, said rib being of maxinnnn depth at the middle of the carline and preferably, as shown, decreasing in depth toward its ends adjacent to which it merges into the body. It may, however, be made of uniform depth throughout, if desired.

The construction described is, as before stated, adapted to receive a wooden lillin piece 2 for the attachment of the ridge-p0 c and puriins; but, if desired, the vertical flanges of the body may be turned downwardly and outwardly to form a central seat 6 for the reception of a ridge-pole and similar lateral seats to receive purhns. i An improved carhne substantially as above described is adaptable to use in connection with any known and preferred ty 0 of roof and, as will be obvious to those amiliar with car construction, is simple, ineirs pensive, and presents increased strength and rigidity without any substantial increase in weight over .those of the same general type heretofore known and used.

I claim as my invention and desire to secure by Letters Patent- 1. A sheet or plate metal roof-carline ha mg a body of channel-section and an inong tegral downwardly-depending longitudinal strengthenin rib or corrugation extending fron its rm' dle portion toward each of its en s.

2. A sheet or plate metal roof-carline having a body of channel-section and an integral downwardlydepending longitudinal strengthening rib or corrugation, of U or channel section extending from its middle portion toward each of its ends.

3. A sheet or plate metal roof-carline having a body of channel-section, an integral downwardly-depending longitudinal strengthening rib or corrugation, extending from its middle portion toward-each=of its ends and downWardly-dependingend flanges;

for attachment to a car-frame.

a. A sheet or plate metal roof carline having a body of channel-section, aninte-i gral downwardly-depending longitudinal 2o strengthening rib or corrugation, extending from its middle portion toward each of its ends, auxiliary flanges turned on its vertical fiangesand extending from each of-its ends for a portion of its length, and downwardlydepend'ing end flanges turned on the metal of the body and the auxilia flan es.

5. 'The combinatlon 0 a s eet or plate =metal ro'of-carline havin a body of channelsection and a downward y-depending longitudinal strengthening rib or oorrugat1on,- an

a filling of'wood resting on zthe bottom ofsthe 'body, on-eaoh side of the ='strengthening-rib,
